Abstract
We study in detail the properties of the accreting corona model for active galactic nuclei and galactic black holes. In this model the fraction of the energy liberated in the corona at a given radius is calculated from the global parameters of the model (mass of the central object, accretion rate and viscosity parameter) and it appears to be a strong function of the radius. The model predicts the relative decrease of the coronal hard X-ray emission with an increase of the accretion rate. The presented description of disc/corona interaction forms a basis for further studies of disc disruption mechanism.
